Answer
120 mod 7 ≡ 1
This means that 7 does not divide 120 → 7∤120
This means that 7 does not divide 120 → 7∤120
Steps Explained:
Simplify the following:
120 mod 7
Also, does 7 divide 120?
Define modulus:
Remainder of a ÷ b
In this case, a = 120 and b = 7
Calculate whole number part:
7 goes into 120 a total of 17 times
7 x 17 = 119
Calculate remainder part:
Remainder = a - whole number
Remainder = 120 - 119
Final Answer
120 mod 7 ≡ 1This means that 7 does not divide 120 → 7∤120
